the sector seven toys? (spoilers potential)

whats the deal with them. i know theyre target exclusives and theyre repaints of cybertron and energon figures but whats their place in the movie story. i know the real gear are kind of the freaks created by the allspark and human experimenting but how do these other figures fit in. are the more creations of human tampering with the allspark? are they cybertronians investigating earth before the arrival of the four autobots? what are they?
